  • Windows Physical Direct Memory Mapping

    - by chrisjleaf
    I'm a bit disappointed there is almost no discussion of this no matter where I look so I guess I'll have to ask. I'm writing a cross platform memory bench marking application which requires direct physical address mapping rather than virtual addressing. EDIT The solution would look something like the Linux/Unix system calls: int fd = open("/dev/mem", O_RDONLY); mmap(NULL, len, PROT_READ, MAP_SHARED, fd, PHYSICAL_ADDRESS_OFFSET); which will require the kernel to either give you a virtual page mapping to the desired physical address or return that it failed. This does require supervisor privileges but that is ok. I have seen a lot of information about shared memory and memory mapped files but all of these reside on disc and are thus not really useful when I'm trying to make a system dependent read. It is very similar to writing an IO driver although I do no need write permissions to the physical address. This site gives an example of how to do it on a driver level using the Windows Driver Kit: NT Insider: Sharing Memory between drivers and applications This solution would probably require Visual Studio which currently I do not have access to. (I have downloaded the WDK api but it complained about my use of GCC for Windows). I'm traditionally a Linux programmer so I'm hoping there might be something really simple I'm missing. Thanks in advance if you know something I don't!

  • What's up with LDoms: Part 9 - Direct IO

    - by Stefan Hinker
    In the last article of this series, we discussed the most general of all physical IO options available for LDoms, root domains.  Now, let's have a short look at the next level of granularity: Virtualizing individual PCIe slots.  In the LDoms terminology, this feature is called "Direct IO" or DIO.  It is very similar to root domains, but instead of reassigning ownership of a complete root complex, it only moves a single PCIe slot or endpoint device to a different domain.  Let's look again at hardware available to mars in the original configuration: root@sun:~# ldm ls-io NAME TYPE BUS DOMAIN STATUS ---- ---- --- ------ ------ pci_0 BUS pci_0 primary pci_1 BUS pci_1 primary pci_2 BUS pci_2 primary pci_3 BUS pci_3 primary /SYS/MB/PCIE1 PCIE pci_0 primary EMP /SYS/MB/SASHBA0 PCIE pci_0 primary OCC /SYS/MB/NET0 PCIE pci_0 primary OCC /SYS/MB/PCIE5 PCIE pci_1 primary EMP /SYS/MB/PCIE6 PCIE pci_1 primary EMP /SYS/MB/PCIE7 PCIE pci_1 primary EMP /SYS/MB/PCIE2 PCIE pci_2 primary EMP /SYS/MB/PCIE3 PCIE pci_2 primary OCC /SYS/MB/PCIE4 PCIE pci_2 primary EMP /SYS/MB/PCIE8 PCIE pci_3 primary EMP /SYS/MB/SASHBA1 PCIE pci_3 primary OCC /SYS/MB/NET2 PCIE pci_3 primary OCC /SYS/MB/NET0/IOVNET.PF0 PF pci_0 primary /SYS/MB/NET0/IOVNET.PF1 PF pci_0 primary /SYS/MB/NET2/IOVNET.PF0 PF pci_3 primary /SYS/MB/NET2/IOVNET.PF1 PF pci_3 primary All of the "PCIE" type devices are available for SDIO, with a few limitations.  If the device is a slot, the card in that slot must support the DIO feature.  The documentation lists all such cards.  Moving a slot to a different domain works just like moving a PCI root complex.  Again, this is not a dynamic process and includes reboots of the affected domains.  The resulting configuration is nicely shown in a diagram in the Admin Guide: There are several important things to note and consider here: The domain receiving the slot/endpoint device turns into an IO domain in LDoms terminology, because it now owns some physical IO hardware. Solaris will create nodes for this hardware under /devices.  This includes entries for the virtual PCI root complex (pci_0 in the diagram) and anything between it and the actual endpoint device.  It is very important to understand that all of this PCIe infrastructure is virtual only!  Only the actual endpoint devices are true physical hardware. There is an implicit dependency between the guest owning the endpoint device and the root domain owning the real PCIe infrastructure: Only if the root domain is up and running, will the guest domain have access to the endpoint device. The root domain is still responsible for resetting and configuring the PCIe infrastructure (root complex, PCIe level configurations, error handling etc.) because it owns this part of the physical infrastructure. This also means that if the root domain needs to reset the PCIe root complex for any reason (typically a reboot of the root domain) it will reset and thus disrupt the operation of the endpoint device owned by the guest domain.  The result in the guest is not predictable.  I recommend to configure the resulting behaviour of the guest using domain dependencies as described in the Admin Guide in Chapter "Configuring Domain Dependencies". Please consult the Admin Guide in Section "Creating an I/O Domain by Assigning PCIe Endpoint Devices" for all the details! As you can see, there are several restrictions for this feature.  It was introduced in LDoms 2.0, mainly to allow the configuration of guest domains that need access to tape devices.  Today, with the higher number of PCIe root complexes and the availability of SR-IOV, the need to use this feature is declining.  I personally do not recommend to use it, mainly because of the drawbacks of the depencies on the root domain and because it can be replaced with SR-IOV (although then with similar limitations). This was a rather short entry, more for completeness.  I believe that DIO can usually be replaced by SR-IOV, which is much more flexible.  I will cover SR-IOV in the next section of this blog series.

  • User Experience Highlights in PeopleSoft and PeopleTools: Direct from Jeff Robbins

    - by mvaughan
    By Kathy Miedema, Oracle Applications User Experience  This is the fifth in a series of blog posts on the user experience (UX) highlights in various Oracle product families. The last posted interview was with Nadia Bendjedou, Senior Director, Product Strategy on upcoming Oracle E-Business Suite user experience highlights. You’ll see themes around productivity and efficiency, and get an early look at the latest mobile offerings coming through these product lines. Today’s post is on the user experience in PeopleSoft and PeopleTools. To learn more about what’s ahead, attend PeopleSoft or PeopleTools OpenWorld presentations.This interview is with Jeff Robbins, Senior Director, PeopleSoft Development. Jeff Robbins Q: How would you describe the vision you have for the user experience of PeopleSoft?A: Intuitive – Specifically, customers use PeopleSoft to help their employees do their day-to-day work, and the UI (user interface) has been helpful and assistive in that effort. If it’s not obvious what they need to do a task, then the UI isn’t working. So the application needs to make it simple for users to find information they need, complete a task, do all the things they are responsible for, and it really helps when the UI just makes sense. Productive – PeopleSoft is a tool used to support people to do their work, and a lot of users are measured by how much work they’re able to get done per hour, per day, etc. The UI needs to help them be as productive as possible, and can’t make them waste time or energy. The UI needs to reflect the type of work necessary for a task -- if it's data entry, the UI needs to assist the user to get information into the system. For analysts, the UI needs help users assess or analyze information in a particular way. Innovative – The concept of the UI being innovative is something we’ve been working on for years. It’s not just that we want to be seen as innovative, the fact is that companies are asking their employees to do more than they’ve ever asked before. More often companies want to roll out processes as employee or manager self-service, where an employee is responsible to review and maintain their own data. So we’ve had to reinvent, and ask,  “How can we modify the ways an employee interacts with our applications so that they can be more productive and efficient – even with tasks that are entirely unfamiliar?”  Our focus on innovation has forced us to design new ways for users to interact with the entire application.Q: How are the UX features you have delivered so far resonating with customers?  A: Resonating very well. We’re hearing tremendous responses from users, managers, decision-makers -- who are very happy with the improved user experience. Many of the individual features resonate well. Some have really hit home, others are better than they used to be but show us that there’s still room for improvement.A couple innovations really stand out; features that have a significant effect on how users interact with PeopleSoft.First, the deployment of PeopleSoft in a way that’s more like a consumer website with the PeopleSoft Home page and Dashboards.  This new approach is very web-centric, where users feel they’re coming to a website rather than logging into an enterprise application.  There’s lots of information from all around the organization collected in a way that feels very familiar to users. In order to do your job, you can come to this web site rather than having to learn how to log into an application and figure out a complicated menu. Companies can host these really rich web sites for employees that are home pages for accessing critical tasks and information. The UI elements of incorporating search into the whole navigation process is another hit. Rather than having to log in and choose a task from a menu, users come to the web site and begin a task by simply searching for data: themselves, another employee, a customer record, whatever.  The search results include the data along with a set of actions the user might take, completely eliminating the need to hunt through a complicated system menu. Search-centric navigation is really sitting well with customers who are trying to deploy an intuitive set of systems. Q: Are any UX highlights more popular than you expected them to be?  A: We introduced a feature called Pivot Grid in the last release, which is a combination of an interactive grid, like an Excel Pivot Table, along with a dynamic visual chart that automatically graphs the data. I wasn’t certain at first how extensively this would be used. It looked like an innovative tool, but it wasn’t clear how it would be incorporated in business process applications. The fact is that everyone who sees Pivot Grids is thrilled with that kind of interactivity.  It reflects the amount of analytical thinking customers are asking employees to do. Employees can’t just enter data any more. They must interact with it, analyze it, and make decisions. Pivot Grids fit into this way of working. Q: What can you tell us about PeopleSoft’s mobile offerings?A: A lot of customers are finding that mobile is the chief priority in their organization.  They tell us they want their employees to be able to access company information from their mobile devices.  Of course, not everyone has the same requirements, so we’re working to make sure we can help our customers accomplish what they’re trying to do.  We’ve already delivered a number of mobile features.  For instance, PeopleSoft home pages, dashboards and workcenters all work well on an iPad, straight out of the box.  We’ve delivered a number of key functions and tasks for mobile workers – those who are responsible for using a mobile device to manage inventory, for example.  Customers tell us they also need a holistic strategy, one that allows their employees to access nearly every task from a mobile device.  While we don’t expect users to do extensive data entry from their smartphone, it makes sense that they have access to company information and systems while away from their desk.  That’s where our strategy is going now.  We plan to unveil a number of new mobile offerings at OpenWorld.  Some will be available then, some shortly after. Q: What else are you working on now that you think is going to be exciting to customers at Oracle OpenWorld?A: Our next release -- the big thing is PeopleSoft 9.2, and we’ll be talking about the huge amount of work that’s gone into the next versions. A new toolset, 8.53, will be coming, and there’s a lot to talk about there, and the next generation of PeopleSoft 9.2.  We have a ton of new stuff coming.Q: What do you want PeopleSoft customers to know? A: We have been focusing on the user experience in PeopleSoft as a very high priority for the last 4 years, and it’s had interesting effects. One thing is that the application is better, more usable.  We’ve made visible improvements. Another aspect is that in customers’ minds, the PeopleSoft brand is being reinvigorated. Customers invested in PeopleSoft years ago, and then they weren’t sure where PeopleSoft was going.  This investment in the UI and overall user experience keeps PeopleSoft current, innovative and fresh.  Customers  are able to take advantage of a lot of new features, even on the older applications, simply by upgrading their PeopleTools. The interest in that ability has been tremendous. Knowing they have a lot of these features available -- right now, that’s pretty huge. There’s been a tremendous amount of positive response, just on the fact that we’re focusing on the user experience.

  • User Experience Highlights in Siebel: Direct from George Jacob

    - by mvaughan
    By Misha Vaughan and Kathy Miedema, Oracle Applications User Experience This is the first in a series of blog posts on the user experience (UX) highlights coming in various Oracle product families. You’ll see themes around productivity and efficiency, as well as a thoughtful approach to pushing UX capabilities into the underlying tooling. Of course, you can also expect to get an early look at the latest mobile offerings coming through these product lines.Today’s post is on Siebel. To learn more about what’s ahead, attend Siebel OpenWorld presentations. Our first interview is with George Jacob, the Group Vice President for CRM Applications. George Jacob Q: How would you describe the vision you have for the user experience of Siebel? A: Contemporary: Siebel runs in all browsers and all browser-capable devices using the latest web technology standards, such as Javascript, CSS, and HTML 5.Productive: Siebel is designed for a user experience that reduces clutter and user keystrokes.User-sensitive: The user experience enables Siebel to adapt easily to site and user preferences.Q: How are the UX features you have delivered so far resonating with customers? A:  Customers are very excited about our refresh of the Siebel user interface framework; the Siebel roadmap and user interface sessions at Oracle OpenWorld last year overflowed. We have had to turn back customer requests to participate in the early adopter program because we had more than we could handle. Customers are calling this a game-changer for Siebel.Q: So the UX highlights are popular? A: Yes, the UX highlights are very popular, although to a certain extent we expected this!  Q: What’s coming in Siebel on a mobile platform? A: Our current mobile offering is based on Windows Mobile (native application), and is fairly mature (over 5 years). The new Siebel Open User Interface Framework, by virtue of working on all browsers, will run – when it is released this year – on tablets and smartphones. This is one of the reasons a number of customers are most excited about our UX changes. Views of Siebel data on mobile devices Q: What are you working on now that you think is going to be exciting to customers at OOW? A: We are working on the Siebel Open User Interface Framework, to be released this year in the Siebel 2012 8.1.1.9 & 8.2.2.2 innovation packs. We are also working on Connected Mobile applications for Sales, Service, Consumer Goods and Pharmaceuticals, and Disconnected Mobile applications for Pharmaceuticals in the same release. We are building specialized applications that exploit the new UI framework for Telco Order Capture and for Life Sciences healthcare professional visits. Our 2012 delivery will be the foundation for further user experience enhancements, next year and beyond.Q: What do you want Siebel customers to know? A:  We are excited to be focused on improving the user experience of Siebel applications, and it is encouraging to see the positive feedback from Siebel customers and partners.If you would like to see more in the Siebel user experience, be sure to check out these sessions at OpenWorld: CON9700 - Siebel CRM Overview, Strategy, and Roadmap CON9703 - User Interface Innovations with the New Siebel “Open UI” CON9705 - Unleash the Power of “Open UI” CON9697 - Mobile Solutions for Siebel CRM

  • Direct Code Support?

    - by Josh Kahane
    A few times in the past I've hit a major wall and simply couldn't progress with a certain aspect of an app as Im a beginner and still learning the ropes (Objective-C specifically). I was curious if anyone knows of any services which support programmers in real time, paid or free and will over video, audio or text chat sit and work a problem out till its fixed and look through your code? I understand Stackoverflow does a super job at this! However Im in need of something a little more tailored where someone can spend a little time to sit and look and what Im dealing with and delve into my a code if need be. Thanks.

  • Web interface with FastCGI or with direct HTTP?

    - by Basile Starynkevitch
    Let's assume I want (for fun at start) to play with some new DSL (domain specific language) idea. And I really want its user[s] (probably only me at first) to interact thru a web interface. I'll probably implement it in C++ (probably using LLVM). Should I use an HTTP server library (like libonion or microhttpd) to talk directly HTTP or should I use FastCGI? In particular, I am noticing that several recent web frameworks (Opa, Ocsigen, ...) do not have any FastCGI interface but only HTTP one.... So my feeling is that FastCGI is really out of fashion.... Any opinions on that? Do you know recently started project using FastCGI ? (and what about SCGI?)

  • Direct X-forwarding

    - by Sean Houlihane
    I'm struggling to set up X-forwarding between 2 different machines on my local network and my ubuntu desktop. I'm able to connect using ssh x-forwarding one one machine, but the other machine (a Qnap TS-219P II) seems to have a less functional build of SSH on it, and I'd rather use a simpler approach. I've set $DISPLAY, and done 'xauth list $DISPLAY' on the desktop, then 'xauth add ' on the remote machine. From the remote machine, I just get xterm xterm Xt error: Can't open display: 192.168.0.4:0.0 Now, oddly, if I connect via ssh -X, there is a different magic cookie for the tunnelled port (but neither seems to work). I'm wondering if there is a port which needs to be enabled to permit X connections from the LAN? If so, how? The proper solution might be to re-build all the packages which are preventing X-forwarding from working on my QNAP machine, but lets assume for the purposes of this question that I've tried building enough packages on that architecture already and want to run X without the overhead of encryption.

  • Ubuntu 12.04 wireless disabled even though the direct connectin (thru modem) is working fine

    Need help with my newly installed Ubuntu 12.04 system (dual booting along with Win 7), even thoguh I can use internet using the modem and directly plugging it, the wireless network is disabled and it says firmware missing. I tried the following options: 1) checking to see if the wireless is disabled using the hot keys (F2 or Ctrl+F2, Fn + F2 keys), the wireless is working fine in Win 7 but not in Ubuntu. 2) I am able directly plug the laptop with the modem and able connect to Internet using Ubuntu. 3) From the top right hand menu bar, te Wireless networks options say "device not ready (firmware missing) and the Enable Wireless checkbox is checked. 4) tried the command "rfkill list" , it shows all are NOT blocked. 0: phy0: Wireless LAN soft blocked:no Hard blocked: no 1: dell-wifi: Wireless LAN soft blocked:no Hard blocked: no 2: dell-bluetooth: BlueTooth soft blocked:no Hard blocked: no 3: hci0 Bluetooth soft blocked:no Hard blocked: no 5) ifconfig command shows eth0 and lo (lcoalhost) up and running but the wlan0 option is not available to show unless I type ifconfig -a, when it shows wlan0 but its down. 6) The command lspci -vvnn | grep 14e4 shows 04:00.0 network Controller [0280]: Broadcom Corp BCM4312 802.11b/g LP-PHY [14e4:4315] {rev 01) 08:00.0 Ethernet Controller [0200]: Broadcom Corp Netlink BCM5784M Gigabit Ethernet PCIe [1434:1698] {rev 10) 7) The file /var/lib/NetworkManager/NetworkManager.state shows all options are true (networking enabled, wireless enabled, wwlanenabled and wimaxenabled all options are set to true). 8) 'additional drivers' in your Dash and/or Preferences do not bring up anything at all. 9) output for lshw -C network shows *-network DISABLED description : Wireless interface physical id: 4 logical name: wlan0 serial: 78:e4_00"43:b6:ab capabilities: ethernet physical wireless Configuration: broadcast=yes driver=b43 driverversion=3.2.0.29-generic-pae firmware=N/A link=no multicast= yes wireless=IEEE 802.11bg

  • Generic Handler vs Direct Reference

    - by JNF
    In a project where I'm working on the data access layer I'm trying to make a decision how to send data and objects to the next layer (and programmer). Is it better to tell him to reference my dll, OR should I build a generic handler and let him take the objects from there (i.e. json format) If I understand correctly, In case of 2. he would have to handle the objects on his own, whereas in case 1. he will have the entities I've built. Note: It is very probable that other people would need to take the same data, though, we're not up to that yet. Same question here - should I make it into a webservice, or have them access the handler?

The redirects are causing performance hits to the site.
